Actually KO2 oxygen rebreathers use chlorate candle to initiate the reaction which produces O2 not CO2.
Chemical oxygen generator - Wikipedia, the free encyclopedia Yes, sometimes. But...there are also other systems that actually make CO2 to get things going. Have had a russian manual describing such a system translated for me. If I recall correctly the CO2 generators was pretty straight forward. A striking pin breaking a container of acid that flows into some carbonate salt giving off CO2 very fast.
